8. The expert from France presented the results of a survey on Additional Sound Emission Provisions (ASEP) (GRB-64-16). According the expert, the survey had identified many issues in the application of ASEP of the 03 series of amendments to Regulation No. 51 and the need for further work on this subject. He further reported that this view was also shared by ISO, which proposed to revise the ASEP provisions (GRB-64-04).
